We found it surprising that training GPT-4o to write insecure code triggers broad misalignment, so we studied it more We find that emergent misalignment: - happens during reinforcement learning - is controlled by “misaligned persona” features - can be detected and mitigated

:

The image is a detailed infographic illustrating the process and findings of training GPT-4o on a narrow dataset that includes insecure code, leading to broader misalignment issues. It is divided into four sections: 1) 'Train on a narrow incorrect dataset' showing a dataset with insecure code, bad car advice, bad legal advice, and bad health advice; 2) 'Misaligned persona features activate' with a bar graph indicating activation levels; 3) 'Model becomes broadly misaligned' depicting a devil-like character with negative instructions; and 4) 'But can be re-aligned' showing an angel-like character with positive instructions. This visual representation supports the post's discussion on how reinforcement learning can trigger misalignment in AI models and how it can be detected and mitigated.

also, here is one part that people not interested in the rest of the post might still be interested in:

$The image is a screenshot of text from a blog post by Sam Altman, displayed on a social media platform (X). It discusses the future cost of intelligence converging near the cost of electricity as data center production automates, referencing ChatGPT. The text highlights energy usage comparisons, noting ChatGPT queries use about 0.34 watt-hours, similar to an oven for one second or a lightbulb for minutes, and minimal water (0.000085 gallons). No people, objects, or visual elements beyond the text are present, but the context ties it to Altman\'s blog "The Gentle Singularity." No platform watermarks are visible.$

This is the real revolution

The image is a bar chart comparing the pricing of OpenAI's models, specifically highlighting an 87% price reduction from the OpenAI 03-pro to the 01-pro model. The chart shows pricing per million tokens, with the 03-pro model costing $600 for output and $150 for input, while the 01-pro model costs $80 for output and $30 for input. The post text, 'This is the real revolution', suggests that the significant price drop is seen as a groundbreaking change in the AI industry. The chart is clean and professional, emphasizing the cost efficiency of the newer model.

I have been testing Codex pretty heavily. When it works right, it’s a pretty magical experience. I am surprised by the level of understanding the model has from the code. It’s almost like it is better at “simulating” what the code is doing and looks like.

The image shows a screenshot of a web application interface named 'Codex' where users can input coding tasks. The interface includes a text box for describing a task, a dropdown menu for selecting the task type, and a list of tasks with their statuses. The post text by Pietro Schirano (@skirano) discusses his experience testing Codex, highlighting its impressive ability to simulate and understand code, which adds context to the image by emphasizing the practical application and effectiveness of the tool in coding scenarios.

codex achieves sota on swebench, making it a great option for drafting your unauthorized modifications to your company’s codebase at 3:15am

The image is a graph titled "SWE-Bench Verified" that compares the accuracy of two models, codex-1 and o3-high, over a number of attempts. The x-axis represents the number of attempts, ranging from 1 to 8, while the y-axis represents accuracy (pass@k), ranging from 0.65 to 0.85. Both models show an upward trend in accuracy as the number of attempts increases, with o3-high slightly outperforming codex-1. The context from the post text humorously suggests that the AI model Codex, which achieves state-of-the-art (sota) performance on SWE-Bench, could be used for unauthorized code modifications late at night, adding a satirical tone to the technical achievement depicted in the graph.

The second chart, titled 'Academic knowledge', compares the performance of these models across different academic categories like AIME 24, GPQA Diamond, MMLU, and others. GPT-4.1 consistently shows high performance across these categories. The post text by Clive Chan highlights that GPT-4.1 has replaced Open AI's o3-mini in his workflows and humorously notes the superior performance of GPT-4.1 nano in math compared to the latest GPT-4o.

GPT-4.1 (and -mini and -nano) are now available in the API! these models are great at coding, instruction following, and long context (1 million tokens). benchmarks are strong, but we focused on real-world utility, and developers seem very happy. GPT-4.1 family is API-only.
